I have a bunch of Arduinos in different places on my property.
I develop the code on a Linux PC, then copy the main.ccp and config.h to a Linux notebook, go the the relevant hardware node and upload the code.
What I noticed is that PIO uploads the previous code, as it it thinks ‘nothing has changed’, and uploads the previous version.
There are two types of compilation results, a short and a longer one:

The shorter version does not re-compile the code, while the longer one does.
Is there a way to force the compilation; either through a CLI or .ini statement?
